[Death on the Reik] Size and Damage calculations breaks equipping vehicle weapon

[moo-man]

From MooMan's homebrew options, have "Size and Damage calculations" active breaks equipping vehicle weapons. You can drag weapons onto the sheet but cannot click "equip" I tried this on several types of boat, and with several weapons

Error seems to be caused by mooSizeDamage, specifically by trying to access the actor.sizeNum on vehicle.
